"Who Peter" is an obvious pun which has been otherwise used by Blue Peter and Doctor Who for cross-promotion. In the BBC Wales era alone, it has been at least twice used to describe various Blue Peter competitions involving Doctor Who. For instance, it was the name of the event which landed Blue Peter viewer, John Bell, a role in Utopia.[3] It was also the — arguably unofficial — name of the competition to design a TARDIS console that was seen in series 5.[4]

↑Technically, Chapman won the "Best Newcomer Award" for only part one, as the second part had not been released at the time of judging. He also won for his then-released body of work for Dene Films, which included Who Peter, Taking a Dive, and The World Changed.
